1 pākaukau Lithium
ʻO ka pākaukau Lithium kahi ʻano pākaukau e hoʻohana ana i ka metala lithium a i ʻole lithium alloy e like me ka mea electrode maikaʻi ʻole a hoʻohana i ka hopena electrolyte non-aqueous.He kiʻekiʻe loa kona ikehu kikoʻī, akā loaʻa iā ia nā pōʻino palekana.ʻO ka mea electrode maikaʻi o ka pā lithium he manganese dioxide a i ʻole thionyl chloride, a ʻo ka mea electrode maikaʻi ʻole he lithium.Ma hope o ka hōʻuluʻulu ʻana o ka pākaukau, loaʻa ka volta a ʻaʻole pono e hoʻopiʻi.Hiki ke hoʻopaʻa ʻia kēia ʻano pākaukau, akā ʻaʻole maikaʻi ka hana pōʻai.I ka wā o ka hoʻouka ʻana a me ka hoʻokuʻu ʻana, maʻalahi ka hana ʻana i nā lithium dendrites, ka hopena i kahi kaapuni pōkole o loko o ka pākaukau, no laila ʻaʻole pāpā ʻia kēia ʻano pākaukau.
Pākuʻi Lithium Ion
ʻO ka Battery Lithium Ion (Lion) e pili ana i kahi pākaukau rechargeable e hoʻohana ana i nā ion lithium ma ke ʻano he mea reactive.Ke hoʻokuʻu ʻia ka pākaukau i ka volta hoʻopau, hiki ke hoʻouka hou ʻia e hoʻihoʻi i ka mokuʻāina ma mua o ka hoʻokuʻu ʻana.Hoʻopaʻa a hoʻokuʻu i nā pahu lithium-ion ma o nā mea hana i uhi ʻia ma nā electrodes, ʻo ia hoʻi, e mālama i ka ikehu uila ma o ka deintercalation o nā lithium ion ma nā mea hana electrode.ʻO ke ʻano o nā ʻona lithium ion ka mea maoli e hoʻohana i ka ʻokoʻa ʻokoʻa o nā ion lithium no ka mālama ʻana a me ka hoʻokuʻu ʻana.ʻAʻohe lithium metala i loko o ka pākaukau, no laila ʻoi aku ka maikaʻi o kona palekana ma mua o nā pā lithium, a ʻoi aku ka haʻahaʻa o ka ikehu kūikawā o nā pā lithium ion ma mua o nā pā lithium.ikehu.
3 ʻO ka ʻokoʻa ma waena o ka pā lithium a me ka pā lithium ion
Ma ke kumukānāwai, ʻokoʻa nā manaʻo like ʻole o nā pākahi lithium a me nā pā lithium-ion.ʻO kahi pākaukau e hoʻohana ana i ka metala lithium ma ke ʻano he mea electrode i kapa ʻia he pākahi lithium, nona ka pākaukau mua.Hiki ke kiola ʻia ma hope o ka hoʻohana ʻana a ʻaʻole hiki ke hoʻohana hou ʻia.ʻO ka mea electrode maikaʻi o ka pākaukau lithium ion he lithium cobalt oxide (a i ʻole lithium metal oxide), a ʻo ka mea electrode maikaʻi ʻole he mea kalapona.I mea e hoʻokaʻawale ai ia mai ka pākaukau lithium maʻamau, ua kapa ʻia ʻo ia ka pā lithium ion.ʻO nā ʻona Lithium-ion nā ʻāpana lua i hiki ke hoʻouka hou ʻia a hoʻohana hou ʻia, ʻo ia hoʻi, kā mākou mau ʻona maʻamau.I ke ola o kēlā me kēia lā, nui ka poʻe e huikau i nā mea ʻelua a kāhea aku i nā ʻeke lithium-ion i hoʻopau ʻia e like me nā pā lithium, kahi e alakaʻi ai i ka huikau o nā manaʻo.
Aia kekahi ʻokoʻa nui loa ma waena o nā pā lithium a me nā pā lithium ion electrochemically, ʻo ia hoʻi, ka volta hoʻokuʻu.ʻO ka maʻamau, ʻo 3.0 V ka paepae hoʻokuʻu o ka pā lithium, no laila ʻo ka volta nominal o ka pā lithium o nā kāmera he nui he 3.0 V, a ʻo ka pākaukau lithium backup o ke kelepona paʻa he 3.0 V. ʻO ka pae hoʻokuʻu maʻamau o ka lithium-ion. Aia nā pila ma waena o 3.6 a me 3.8 V. I kēia manawa, ʻo ka hapa nui o nā ʻāpana lithium-ion kelepona paʻa he 3.7 V, a ʻo kekahi kekahi he 3.8 V. Hiki ke hoʻohana ʻia kēia ʻano uila no ka hoʻokaʻawale ʻana i nā pā lithium-ion mai ka lithium. nā pila.I ke ola, ʻaʻole koʻikoʻi ke kāhea ʻana i nā pihi i hoʻohana ʻia i nā kāmera, nā kamepiula a me nā kelepona paʻa e like me nā pā lithium rechargeable a i ʻole lithium batteries.Kapa ʻia ʻo ia ʻo nā pākahi lithium ion a hoʻopau ʻia ʻo Li-ion a i ʻole Li+.ʻO ka pōkole no ka pā lithium he Li, me ka ʻole + (hōʻailona ion maikaʻi).
